Abstract

The MLVDS interface can support up to 500Mbps data rate and a wide common mode voltage range, and has strong ESD protection characteristics, supporting hot swapping function. MLVDS solves electromagnetic interference (EMI) problems by controlling the voltage swing rate and output amplitude of output data. In addition, MLVDS also retains LVDS low-voltage differential signal characteristics, which can further reduce electromagnetic interference and drive multiple transceivers to achieve interconnection applications, Featuring high transmission rate, low power consumption, and low noise. The main control system of the Ka simulated phased array antenna wave control system controls multiple sub wave control components through the MLVDS bus. The MLVDS bus between the main control and sub wave control adopts a one-to-eight structure, and the MLVDS transmission rate is required to be 50Mbps, with reliable and stable transmission. From the perspective of reliability and derating design, the MLVDS bus of the system is required to transmit stably at a transmission rate of 100Mbps. Based on this, establish a testing platform to verify the reliable transmission of MLVDS one to eight bus at a transmission rate of 100Mbps.
